SPECIFICATION forming part of Letters Patent N o. 686,788, datedNovember 19, 1901. Application iiled February 4, 1899. Serial No.704,566. (No model.)

To a/ZZ when?, t may concern:

Be it known that I, FRANZ WAGNER, a subject of the King of Bavaria, anda resident of Nuremberg, Bavaria, Germany, have invented certain new anduseful Improvements in Means for Lubricating Pistons and Slides ofLocomotives, of which the following is a specication.

My invention consists in an improved system for lubricating the workingparts of locomotive-engines.

In the accompanying drawings, Figure lis a side view of the reservoirfor the lubricant, the cylinders from which the lubricant is forced tothe parts to be lubricated, and the attached parts. Fig. 2 is a planview of Fig. l. Fig. 3 is a sectional View of the spraying device forthe lubricant. Fig. 4 is a plan View of Fig. 3. Figs. 5 and 6 aresectional views of a distributing device, showing the distributing-valvein two different positions. Fig. 7 is a side View, and Fig. 8 a rearView, of a locomotive with my improvement attached. Fig. 9 is a detailside view of the right side of Fig. l.

The reservoir for the lubricant D is arranged in the cab of thelocomotive, and to this is connected pipes D DX, which lead separatelyto two cylinders P P. Withthese pipes a three-way cock C is arranged,and when this is properly turned the lubricant will iiow from thereservoir into these cylin-l ders, to be subsequently forced therefromto the parts to be 1ubricated-thatis, the cylinders and slide-valvesofthe engines. After the forcing-cylinders P P have been filled thethree-way cock is turned into the position shown in Fig. l, so as toopen communication between the forcing-cylinders P P and the sprayingdevice E, supported by a bracket E upon the framework E2, and thuscutting 0E the supply from the reservoir D. The frame E2 also serves tosupport the forcingcylinders P P. The plungers, which are movable withinthe cylinders, are connected with each other by a common cross-piece ortraverse T and are moved up and down, as may be required, in the usualmanner by the rotation of the male screw T', set in a femalescrew-thread of the traverse T. The revolution of the male screw takesplace in the usual manner by a ratchet-wheel, which is actuated from thecross-head or one of the drivingwheels, or it takes place by hand by acrank k after disconnecting the said ratchet-wheel. The lubricant fromthe force-feed cylinders P P passes to the spraying device through thepipes Dl D and their continuations D,

Figs. l and 9, and from the spraying device the oil passes to the partsto be lubricated, as will be hereinafter described.

The spraying device E comprises a casing having therein two valves e o2,which control chambers x/ 002 in the casing. These valves are arrangedto close toward the oilsupply pipe D, and the chambers m200111-municate, by means of openings l 2, respectively, with a pipe L, whichleads from the boiler of the locomotive. This pipe and its relation tothe other parts are shown in Figs. 2, 7, and 8, the latter figuresrepresenting the pipe as being connected with the boiler. The chambersa3' 1:2 have, respectively, ports or nozzles 3 4, with which connect thepipes S 9, leading, respectively, to the right and left hand cylindersof the engine. The pipe 8 is shown in Figs. 7 and 8 as running along thesame side of the boiler as the pipe 9; but at its forward end it extendstransversely under the boiler to the right-hand cylinder. The stems ofthe valves o @zare guided inplugs 5 and 6, which are screwed into thecasing of` the spraying device. The steam, entering the spraying deviceby Way of the pipe L, passes to the right and left over the valves o'lv2 and through the nozzles 34, and by this action the oil enteringthrough the valves lu' v2 is taken up, atomized, and is forced throughthe pipes leading to the steam-cylinders. I interpose in theconnecting-pipe leadingfrom the spraying device tothe engine-cylindersadistributing device V, one of which is located near each of the saidcylinders. The function of each of these distributing devices is tosupply the oil automatically and as required either to the slide-valveor to the piston of the engine. Each distributer comprises a casingcontaining a valve-chamber and a valve 16. A port 13, Fig. 5, isconnected with the pipe 8 or 9, leading from the spraying device, andthrough this the distributer receives the steam and atomized lubricant.A port 12 is connected by a pipe 18, Fig. 7, with the cylinder 30 of theengine, so as to supply the piston thereof with oil, while a port 11 isconnected by a pipe 32 with the slide-valve casing 31 of the enginethrough any suitable connection. (Not shown.) The valve 16 is of doubleformation-that is to say, the piston has a conical valve portion at itsupper end and a conical valve portion at its lower end-and when in itslowest position its lower portion 14 is seated to close the port 11,leading to the slide-valve casing, and while in this position the steamand sprayed oil can pass through the port 12 to the cylinder, the stemof the valve being grooved or suitably formed for this purpose. Thevalve is normally pressed down by a spring 19 and by its own weight.When the engine is running under steam, the steam from the slidevalvecasing entering through the port 11 forces the valve 16 upwardly untilthe npper conical valve portion contacts with the upper valve-seat, andthus opens communication with the port 13, as in Fig. 6, so that thesprayed oil may pass to the slidevalve and lubricate these parts, and,mingling with the live steam, the lubricant will enter the cylinder asthe slide-valve admits the steam lirst to one end of the cylinder andthen the other, as in the ordinary operation of these parts. When steamis shut oft and the engine continues to run, there is no pressure ofsteam entering through the port 11, and the valve 16 will then be freeto fall,which it will do by gravit-y and also by the power of the spring19 and by the steam which may be in the valve-chamber above the valve,which was admitted previously through the port 12 from the cylinder whenthe parts were under steam. The valve now assumes the position of Fig.5, and the lubricant will pass to the cylinder through the port 12. Asthere is no steam-pressure left in the slide-box when running Withoutrsteam, the piston 16 of the distributing-valve is not pressed upward anymore, and the piston must therefore assume the position shown in Fig. 5.

The purpose of the arrangement of the two press-cylinders P P in lieu ofa single one is merely a structural measure, as it simplifies theactuatinggear. Each of the cylinders serves to force the oil into thecorresponding atomizing-valve o or o2, which latter feed the atomizedoil to one cylinder side each. With correct position of the cock C theoil iiows from the tank D by its Vown weight to the cylinders P P, or itcan be forced into the cylinders by firmly screwing down the lid orcover provided on the tank.

I claim- 1. In a central lubricating apparatus for locomotives, thecombination of a reservoir D, a double spraying device E,distributingvalves, double force-feed cylinders P, P, a three-way cockby which the cylinders P P can be connected either with the reservoir Dor the double spraying device E, the said distributing-valves beingarranged in proximity to the steam cylinders, said distributingvalvesbeing connected by pipe-conduits with the spraying apparatus and withthe slidevalve casing andcylinder, substantially as described.

2. In a central lubricating apparatus, the spraying device, adouble-acting distributingvalve, the chamber of which communicates bymeans of a lateral port 13, with the spraying device and by ports 11 and12, with the slide and the cylinder-chamber respectively, and said valvebeing provided with a piston 16 and two conical seats 14 and 15 in sucha manner that the valve, when the locomotive runs under steam, ispressed by the steam admitted through the lower port 1l upon its npperseat and allows the lubricant to reach the slide, while, when runningwithout steam, the valve is pressed upon its lower seat and thelubricant is conducted through the port 12, leading to thesteam-cylinder.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

FRANZ WAGNER.
